Safety in the Chemical LaboratoryChemistry 550


Objectives

Demonstrate what we know about risk and injury

Discuss why safety is a hard sell

Outline the importance of this class

List a few things you can do to promote a culture of safety

Objectives



What we know about risky behavior

People will take risks when the benefit is certain and the hazard is unknown

People will take risks when the benefit is certain and the hazard is uncertain

People will take greater risks following positive results from previous risk taking

People will stop taking risks when the benefit is uncertain or the hazard becomes certain

What we know about risky behavior


Laboratory accidents

Laboratory Accidents


Why is safety a hard sell

  • Safety isn’t “cool” hazard is unknown

  • Unknown rules will always be broken

  • There is no “lack of communication”

    • Only “good” or “bad” communication

  • Fixes are more popular than prevention

  • Too much positive experience with taking risks

Why is Safety a “hard sell”?


Too much positive experience with risk
Too much positive experience with risk hazard is unknown

Heinrich’s Triangle


Why a class about safety

Fluorine gas inhalation hazard is unknown

Graduate Student working alone with 5% fluorine gas

Gas leak in area with improper ventilation

Student suffered pulmonary edema

Corrective actions included written fluorine filling and emergency procedures

What can be done to prevent injury

Training hazard is unknown

Modify behavior

Lead by example

Right tool for the job

Communicate lessons learned

Know the “traps” that cause injury

What can be done to prevent injury?


Modify behavior not just facilities
Modify behavior, not just facilities hazard is unknown

“Swimming pools can be dangerous. To protect people, one can install locks, put up fences, and deploy pool alarms. All of these measures are helpful, but by far the most important thing that one can do is to teach them to swim.” (Thornburgh & Lin ).
